I have to be honest and say that I am not quite sure why I love this so much, but I do. It is gentle, it smells delicious (all the citric acids!), it's foamy, and not drying at all. I have had my first bottle of this for 7 months, and I thought I was getting low. I freaked out bought another one around a month ago and haven't even opened it yet! What I'm trying to say is, this lasts forever! I use...read more it AM and PM, a pump and a half at a time, and it's lasted me this long. Hallelujah I finally found my Holy Grail cleanser.— 5 years, 11 months ago
